Crewed and uncrewed carrier aircraft mix

What is the best ratio of crewed to uncrewed aircraft on aircraft carriers?

A possible starting ratio is two crewed aircraft for every uncrewed one, followed by parity and eventually a larger uncrewed share.

A possible starting mix would place two crewed aircraft aboard for every uncrewed aircraft. A later carrier air wing might reach parity, then move toward one crewed aircraft for every two or three uncrewed aircraft. The progression is conditional rather than a fixed procurement plan. It envisages a gradual shift instead of the immediate replacement of crewed aircraft.
